10 years nn-System: new era in the standard for circular saw blades
A great feat of engineering: Before the LEUCO nn-System DP Flex saw blade was introduced, the state of the art was to use a specific saw blade for each material to reach optimum cutting results. The nn-System DP Flex combines quality and versatility and can also handle critical materials such as CFRP. Quiet and universal.
A clean affair all round: The nn-System saw blades cover a wide range from D 70 to D 350 for numerous applications. Since fall 2023, the system has been provided with a “topcoat” coating which protects the saw blades against adhering contamination and is easy to clean.
The brain behind the patented nn-System: Dr. Dominique Fendeleur, Head of Research & Development for circular saw blades and finger jointing tools at LEUCO.
The revolutionary nn-System (no noise) by LEUCO marks the turn of an era in the product standard of circular saw blades. The essence of the innovation is a tool geometry with extremely small gullets. The effect is a significant reduction of noise during idling and operation combined with high cutting quality and usability for various materials. The father of the saw blade system and master of quiet tones, developer Dr. Dominique Fendeleur, looks back on the milestone in woodworking.
Dr. Fendeleur, the nn-System focuses on noise reduction. Was that your goal?
Yes. We at LEUCO are very innovative and constantly endeavor to improve quality, efficiency and sustainability. This also includes the reduction of noise pollution of the saw blades particularly while idling.
Why is the noise reduction so important, especially when idling?
Because the saw blades are idling more often than they are cutting. This is why everyone in the woodworking industry is familiar with saw blades that whistle when idling. Anyone who is directly or in the immediate vicinity of the saws is particularly affected. The entire working environment therefore benefits from our nn-System.
By how much is the noise reduced?
With the nn-System saw blades, we obtain a noise level reduction when idling of up to 6 decibels compared to conventional circular saw blades. The LEUCO DP Flex saws equipped with the nn-System therefore immediately attracted attention when introduced to the market because they were unusually quiet. With a noise level of just around 70 decibels when idling, the wearing of hearing protection is virtually a thing of the past.
How did the competitors react to the quiet saw blades?
All relevant manufacturers of saw blades try to offer similar solutions. This proves that the market launch in 2014 really means an important innovation for our industry segment.
The nn-System saw blades also differ visually from others.
Exactly. This is also something really new. Due to the extremely small gullets, the teeth are hardly visible. The saw blades equipped with nn-System look like a perfect disc. Therefore, it not only makes less noise, it also offers greater safety.
Do the small gullets affect the performance of the saw blades?
Absolutely not. The saw blades feature the same high cutting quality and long edge life as comparable LEUCO products. On the contrary, the small gullets and the focus on noise reduction have had an influence on the tool development in this industry segment over the last 10 years.
What other innovations does DP flex offer?
The saw blades are very thin, with a cutting width of just 2.5 millimeters. The cutting pressure is noticeably lower, thus saving energy. The saw blades can be used for various materials and are even suitable for highly abrasive materials.
They offer an excellent cutting quality and long edge life
Which saw blades are equipped with the nn-System?
The nn-System is available for different diamond- and carbide-tipped applications: main saw blades and conical scoring saw blades for classic pressure beam machines and clipping saws for through-feed machines. Even our diamond-tipped all-rounder DP Flex is equipped with this technology, ideally suited for table and clipping saws, vertical panel sizing saws, CNC and through-feed machines as well as for portable saws
What conclusions do you draw from this development?
With the no-noise system, we have ushered in a new era in the product standard of circular saw blades. Finally we can say: our products are industry leading.
Dr. Fendeleur, many thanks for this interview.
